The usual experience would be to have three sitting weeks. The House would sit Tuesday, Wednesday, and Thursday of each week.
We have a four-week sitting period starting next week which will include the budget. The budget's usually delivered around the end of May each year, and that would be the time the House would probably sit for the most weeks, and potentially also for the greatest number of hours.
I mentioned earlier that extended sittings have to a large degree replaced the use of urgency, but during the budget, particularly if there are measures that might be going to increase a tax or an excise on something, often that will be passed under urgency as soon as the budget's delivered. That would be one of the occasions where the House may well sit from Thursday into Thursday night, possibly into Friday, or even into Saturday, but it's really just about the only time of the year that would happen.
